Does he want me to be his gf?

there's this guy I've been friends with for a long time, and we always talk on facebook and email. he can only talk to me online because he lives in another city, but it's not very far away from mine. he flirts with me and compliments me, and he hinted that he thinks I'm attractive but he didn't say it directly, so I think he might be shy. he also invited me down to his state to visit him at his family's place where he lives. does he want me to be his gf? what do you think?
